Subscale Jet Engine Testing Services

Test Devices Inc. (TDI) provides subscale jet engine testing for customers in the aerospace industry who are looking for a more affordable and practical way to gather relevant test data for materials, coatings, sensors for new engines in development.

This type of testing is a convenient option for designing and performing your test in a relevant environment to accurately capture the complex interactions of the “elements” in the operating gas turbines.

Why Subscale Jet Engine Test?

Engineers and scientists working on the development of new materials, coating systems, sensors and part designs for new engine need test data to evaluate and refine their work. The type of data is also needed to validate the damage mechanisms, develop and refine the diagnostic and predictive models used in safeguarding the dependable operation of the fleet of gas turbines and jet engine in various services including defense.

High performance machines, such as jet engine and gas turbine parts needs to endure arduous environment for extended period of time and perform its function reliably time after time. The parts designed for combustors and turbine systems are subjected to harsh environment resulting from the combined effects of high temperature, combustion gas products and the CF load for rotating parts.

Pursuing a full-scale engine test as a means of collecting all required engineering data is an impractical, uneconomical, and frankly, impossible exercise in the early stages of development work. Subscale jet engines (also known as mini/micro turbines) provide an opportunity to bridge the information gap that currently exists within the testing capabilities available to jet engine designers and engineers.

Measuring the data from a full-scale engine test would be as close as one can get to a realistic representation of part and equipment operation, but this testing typically requires significant preparation and a substantial budget. In some cases, conducting a full-scale engine test may be unrealistic.
